the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
(Empty space will get OSA options, that I add tomorrow or so)
- Removed a lot of old unused variables in renderdata. Also meant I had
to remove this from python API... please check if this gives valid
scripts?
- Cleaned up bad formatted code for FFMPG buttons (spaces instead of tabs)
with Ton on IRC. This feature was old, something of a hack and didn't really
work well with the modifier stack. To paraphrase Ton: We want to make blender
higher quality, so poorly thought out code should be removed, or replaced
with decent implementations.
Here's the full release log with example file.
http://www.blender3d.org/cms/Render_Baking.827.0.html
For people who don't read docs; just press ALT+CTRL+B on a Mesh
with texture faces!
Todos:
- maybe some filter options extra?
- Make normal maps in Tangent space
eg.
ret_val = ob.join(objects)
Now it dosent depend on the current selection, or change the selection context.
Made respective join_* functions return 0 if the join was not mode, 1 when it workes.
Set the option in EditMode, in 2nd mesh tools panel. It only works on
transform options now (grab/rot/scale), and of course assumes a near-
perfect symmetrical mesh. Mesh Object itself can be on any location
though (and rotated etc).
- Set the button in Paint Panel, Edit buttons context
- It assumes the mesh to be near-perfectly mirrored. Current threshold is
set to 0.0001 (maximum difference allowed).
In order to evaluate proper mirroring, a new option will be added in
Mesh editmode later.
- When the flipped group doesn't exist yet, it creates the group
- Of course this doesn't work for mirror modifier!
New: Select/activate flipped bone or vertex group
- Press SHIFT+F in PoseMode or WeightPaint mode to get the flipped bone.
Is especially to see while painting if the mirror copying works OK.
New: "Apply Envelope to VertexGroup" uses X-mirror option too.
Todo; check on mirror vertex painting, and mirror Mesh editmode....
The implementation is based on a 8x8x8 Octree, where vertex locations are
stored. Vertices on the threshold boundary of an Octree node are filled in
the neighbour nodes as well, ensuring that the lookup works with threshold.
The current size of the Octree gives good speedup, even for 128k vertices
it only needs 256 lookup cycles per checked vertex.
Same code could be used for the bevel tool for example.
src/meshtools.c:
int mesh_octree_table(Object *ob, float *co, char mode)
- mode 's' or 'e' is "start octree" or "end octree"
- mode 'u' is "use", it then returns an index nr of the found vertex.
(return -1 if not found)
to normalised coordinate (convention in blender, helps with
halo)
- removed vertexnormals(), vertexnormals_mesh()
- removed CTX_NO_NOR_RECALC (always assume already calculated)
- change NMesh.c to call mesh_calc_normals
- chance load_editMesh to call mesh_calc_normals after done
converting instead of using editmesh normals
- update recalc_editnormals to also calc vertex normals (whats
4 more adds and a sqrt among friends)
Its hard to believe, but it just might be the case that there
are only two places mesh normals are calculated now (renderer
and kernel)
Render:
- New; support for dual CPU render (SDL thread)
Currently only works with alternating scanlines, but gives excellent
performance. For both normal render as unified implemented.
Note the "mutex" locks on z-transp buffer render and imbuf loads.
- This has been made possible by major cleanups in render code, especially
getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct
OSA or using Materials or Texture data to write to.
- Made normal render fully 4x32 floats too, and removed all old optimizes
with chars or shorts.
- Made normal render and unified render use same code for sky and halo
render, giving equal (and better) results for halo render. Old render
now also uses PostProcess options (brightness, mul, gamma)
- Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer
after render. Using PostProcess menu you will note an immediate re-
display of image too (32 bits RGBA)
- Added "Hue" and "Saturation" sliders to PostProcess options
- Render module is still not having a "nice" API, but amount of dependencies
went down a lot. Next todo: remove abusive "previewrender" code.
The last main global in Render (struct Render) now can be re-used for fully
controlling a render, to allow multiple "instances" of render to open.
- Renderwindow now displays a smal bar on top with the stats, and keeps the
stats after render too. Including "spare" page support.
Not only easier visible that way, but also to remove the awkward code that
was drawing stats in the Info header (extreme slow on some ATIs too)
- Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping
defines.
- I might have forgotten stuff... and will write a nice doc on the architecture!
logical parts, and include files altered to denote internal and external
functions.
include/editmesh.h: internal calls for editmesh_xxx.c files
include/BIF_editmesh.h: external calls for these files
src/editmesh.c: basic alloc/lists and in/out editmode, undo, separate
src/editmesh_lib.c: basic utility calls for all editmesh_xxx.c (no UI)
src/editmesh_add.c: add prim, add duplicate, add vertex/edge/face (UI)
src/editmesh_mods.c: selecting, transforming (UI)
src/editmesh_loop.c: loop tools like knife, loop select, loop subdiv (UI)
src/editmesh_tools.c: other tools (extrude, spin, etc) (UI)
And a new file:
src/meshtools.c: tools for Mesh outside of editmode (normals, draw flags)
